I know when we first arrived my visa from NZ would not work in all machines so try a different ATM. I now don't bother using that one at all as we have local cards, it saves the worry about whether it's going to work or not. Our ones from home have a four digit pin but here it seems to be six digits, don't know whether that makes a difference or not. Best of luck and BTW did you bring your dog? I wish we had :(
